The comment has come up for several project so far and know that this partiualr problem is going to keep coming up in upcoming projects. We have a building that has one unisex restroom, and the LEED review comment was that the Total Daily Usage Rates needs to be adjusted accordingly. I know how to calculate the total daily usage, however my problem is this by how much do you change the usage by? For example we have two building where this has come up, one building had a only one other urinal while the second building had 12 urinals. How do you justify how much you change the daily usage? Is there a standard for this type of adjustment.
Thanks

Hi, did you received any response to this issue? We have also unisex restrooms and we have been asked by the Rewiever that the Total Daily Usage Rates needs to be adjusted accordingly. I also know how to calculate the total daily usage, however my problem is also this by how much do you change the usage by?

In many cases unisex toilet rooms do not provide a urinal. If this is the case with your unisex toilet rooms, the default values based on a 50/50 allocation is not reflective of the Male usage rate. Since the form calculator default for Male FTE is 2 urinal uses and 1 toilet use, you will need to adjust the unisex toilet calcs to accommodate for the lack of a urinal in these rooms. In other words, you would need to override the template's default value and count the Male usage at 3 toilet flushes.
